Production Advantages of Light Magnesium Oxide

Magnesium oxide is widely used in flame retardants and medicine because of its high activity, light weight and looseness. It is one of the functional materials with a bright future. Light burning magnesia, magnesia is a kind of product with large output and wide use in inorganic materials. According to its use, it can be divided into fused magnesia, industrial magnesia, heavy magnesia, special magnesia for friction materials, medical magnesia and metallurgical magnesia. Its magnesia content is more than 99.0%, which is called high purity magnesia. So, what are the advantages and disparities of magnesia production in China?

(1) Advantages

1. Our country has abundant magnesium resources, not only seawater, brine and other liquid resources, but also magnesite, dolomite, brucite and other natural mineral resources, which provide a solid resource advantage for the development of high-purity magnesium oxide in our country.

2. Our country has abundant energy and low price. It has energy guarantee to produce high purity magnesium oxide.

3. Our country has many kinds of raw material routes to produce magnesia. Especially in the past ten years, dolomite carbonization has made great progress and formed its own characteristics in technology and equipment. Scientific and technological achievements have been constantly emerging and applied in production practice. The successful preparation and application of magnesium-containing calcium carbonate has largely solved the problem of dolomite. Pollution problems caused by fossil carburization. In recent years, the traditional brine magnesium salt is developing toward high purity, high added value, functionalization and functional products.

4. Special Magnesium Oxide products are developing rapidly. Various kinds of active Magnesium Oxide, Magnesium Peroxide, Special Magnesium Oxide (Fusion, Silicon Steel, Electronics, High Purity, etc.) and Special Magnesium Oxide for Conveyor Belt have been put on the market one after another.

(2) Gap

1. Because of the small scale of production, poor equipment, and the failure to adopt new technology and equipment, the quality of magnesium salt products in China is unstable, and the consumption of material and energy is high.

2. Magnesium salt production in China is still in the stage of crude primary products production, far from meeting the needs of national economic development. It is understood that China is a major producer of magnesium salts, according to the statistics of the United States, magnesite resources rank first in the world, including Dashiqiao magnesite reserves in Liaoning Province; seawater and salt lakes are also rich in magnesium resources, and have excellent conditions for the development of magnesium salts products. However, compared with the advantages of abundant resources and high grade, the production of magnesium salt in China is still in the production stage of crude primary products, which is far from meeting the needs of national economic development. Therefore, in order to open up new uses of magnesium salts, we should vigorously develop the production of fine products of magnesium salts, especially the development of special magnesium oxides for different uses, such as fused magnesia frits, high purity fused magnesia, the production of magnesia for refractories, ceramics and electrothermal appliances, the application and development of fibrous magnesium salts and high purity magnesium salts.

3. In recent years, although scientific research achievements of fine magnesium salts have been emerging, such as activity, electric melting, silicon steel, high purity magnesium oxide, etc. have been continuously put into the market, the variety and quantity can not meet the domestic market demand, let alone export, because the production of fine magnesium salts is small, which also seriously affects the economic benefits of magnesium salts enterprises.
